Mesenchymal Stem Cell Extracellular Vesicles for the Treatment of Recessive Dystrophic Epidermolysis Bullosa Wounds
INVESTIGATIONAL PRODUCT: AGLE-102 is an allogeneic extracellular vesicle (EV) product derived from normal donor mesenchymal stem cells (MSCs). INDICATION AND RATIONALE: The aim of the study is to assess the safety and efficacy of AGLE-102 in the treatment of lesions in subjects with Epidermolysis Bullosa (EB). STUDY DESIGN: This is a phase 1/2A, randomized, multi-center, study to assess the effectiveness and safety of AGLE-102 on lesions in subjects with EB.
• Subjects must be 6 months or older at screening.
• Subjects who have a confirmed diagnosis of DEB based on electron microscopy, immunomapping, or genetic testing. Subjects with severe DEB (e.g., RDEB patients with absent Col VII/no anchoring fibrils) and milder forms of DEB (e.g., RDEB patients with reduced Col VII and/or anchoring fibril levels) are eligible.
• Presence for at least four weeks of two 10 - 50 cm2 wounds (unroofed EB erosions) at least 4 inches apart that can be considered similar enough in size, wound location and expected healing characteristics to be a matched pair. Neither index wound may have been treated with any local (topical, subcutaneous, etc) or systemic therapeutic other than standard of care treatments described in this protocol (i.e. local or systemic antimicrobials to control infection, topical anesthetic and oral analgesics if required) in the past 3 months prior to screening.
• Females of childbearing potential must have a negative urine or serum pregnancy test at screening and agree to continue use of an acceptable form of birth control throughout the duration of the study. Acceptable forms of birth control include oral, implant, injectable, and transdermal contraceptives; an intrauterine device; or other forms considered acceptable by the investigator. A female subject is eligible to participate if she is not pregnant, is not a woman or childbearing potential (WOCBP), or is a WOCBP who agrees to follow the contraceptive guidance above.
• Post-pubertal males who agree to use an acceptable method of contraception for the duration of the study.
• Subjects 18 years of age and older must be capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Subjects under the age of 18 years must be capable of giving assent (if age-appropriate), and/or they must have a guardian capable of providing consent.
• Willing to comply with the protocol requirements.
